A phased mining plan is adopted based on the mining technological conditions of the deposit in Zhaodianzi Iron Mine, Hebei Province, so as to create conditions as planned to achieve partial in-pit dumping of the overburdened waste. Therefore, area of the allocated dumping site can be reduced and the ecological environment can be protected. In this paper, a detailed presentation is given of the phased mining scheme, the technology of in-pit dumping and the management of in-pit dump. An evaluation is given of in-pit dumping in the mine concerned.
